    Blind mounting APC to a rock

    I have a customer that wants me to route out his logo and blind mount it onto a large stone (I think it is sandstone because it was sandblasted at one time). What I've came up with is cnc riuting 2 logos for each side out of 6mm ACP & drilling counter sunk holes into the back logo then mounting anchors into the stone & bolting the back logo sold then using some type of epoxy to mount the front logo to the back logo. All hardware MUST BE stainless I don't want it to rust.

    My questions does this sound like the most perminate way to do this?

    Will the sandstone hold the anchors? & what are the best anchors to use in sandstone for durability?

    What type of adhesive / epoxy would be best to mount the 2 logos together? I dont want to see a gap between the 2 pieces. Has anyone ever used any of the Lords adhesives?

    Thank you
    Gary

    Do you intend to have the logo stood away from the sandstone or flush up against it?

    I like to use 3M VHB Double sided tape or Soudal TRex-FastGrab adhesive. In both cases, you need to sand/scotch brite the ACP and clean with IPA beforehand for a super bond.

    Sometimes I undersize the second layer so it cant be seen easily.

    I want to have between .5" to 1" standoff. The sandstone is not smooth, it is basically a large sandstone boulder / rock so I don't think the 3m VHB would hold by itself. I'm not familiar with the Soudal Trex product so I'm not sure about it but I was figuring that I would need some type of mechanical fasteners.

    Thank you
